A fiery low-flying object that lit up the Melbourne skyline last night has created a buzz among locals wondering about the origins of the dazzling object.

The spherical object flew from west to east about 8.40pm AEDT.

Astronomers believe a the object was probably a meteor.

TODAY readers wrote in with first-hand accounts of the fireball.

"It was very low in the sky, going from west to east, it had a large burning ball at the front with a thin trail behind it," Yvonne Greig said.

"I was looking out towards the city and I saw a comet, it was white in colour, had a very big trail behind it — I was waiting for it to hit earth, it seemed to be that close," Paul Zuegn said.

The white projectile left behind a substantial trail, but Astronomical Society of Victoria spokesman Perry Vlahos said it would not have posed a threat.

"Despite what people saw in reality it is something quite small, and was probably no bigger than a marble," he told the Daily Telegraph.

"It is certainly not something for people tobe concerned about."

It is the second major piece of space debris to fly across Melbourne skies in a week.

Last Monday a similar meteor prompted locals to call Tullamarine Airport fearing there had been a plane crash.
